Beit known that I, CAnMAN M. SIMPSON, a citizen o'l .the United Statesoi America, re siding' at illillvale, in the count-y of Allegheny andState ol Pennsylvania, have invented certain new and uselullniprmeinents in Rails, ol" which the following,` is a specification,rel'crence beingr had therein to the accompanying drawings.

This invention vrelates` to certain new and useful improvements inrails; and the priniary ohject oll the invention is to provide a novell'orin ol" rail which will he practically jointless. VIn this connectionl have devised a rail particularly adapted for steam, electric, or trainrailways, and in construct inf; my iniprovved rail lorni the saine ol' aplurality ol sections which-are joined together to provide a continuoustread lor rolling-stock that passes over the saine. l have aimed to pronvide a rail the tread or hcadot which can he easily and quickly renewedat any desired time without removing the entire rail.

It is a. well-known fact that considerable trouble is experienced inremovingr the ordi nary spikes to renew a section ot rail and also whena section has once been removed the saine spike-holes of the ties cannothe again used. rlhis permits water to enter the old holes in the tie andin the course ot time renders the tie useless. By iny improved jointlossrail it will not he necessary to reinove the spilies ol" a rail when itis desired to renew the wearing-surface or head of the rail, and in thisnianner a great saving is accomplished in the ties by increasing thelongevity oi the saine. l have made allowances 'for the expansion andcontraction of my improved rail, and the detail construction of the railwill be hereinafter more fully described andl claimed. i

-Referring to the drawings acoinpanying this application, like nunieralsof reference designate corresponding parts throughout Figure 1 is a sideelevation oi'a portion oi a rail. Fig. '2 is a longitudinal sectionalView of the saine. Fig. 3 1s a cross-sectional view taken on the line to; of Fig. 1. Fig. 4 is a perspective View olE a portion of a rail.Fig'. 5 is a similar View of the tread-seetion of the rail, and 6 is asimilar View of the basesection oi the rail.

To put iny invention into practice, 1 conn struct my improved rails of aplurality of sections, said sections being joined together at placesthroughout the rail to l'orni practically a jointless rail. In Fig. 1ol" the drawings i have illustrated a portion et a rail wherein twotread-sections l l are shown and three hase-sections 2 2 2. Thebase-sections consist ot base-llanges 3 3 and upwardly-extendingparallel weh-flanges 4 4, said flanges being provided with aliningropenings or slots 5 5 at their ends and 6 6 intermediate their ends.

The tread-sections 1 consist of a web 'portion 8 and a head or treadportion 9, said head or tread portion heilig' similar to the ordinarytype ol rail at present used. 'lf he wel) portions of the sections 1 areprovided viirh elongated lopenings or slots 10 1() adjacent to theirends and 11 ll intermediatetheir ends.

ln asseinhling?r the sections oi` a rail the hase-sections .2 l .2 aresecured to the tics or foundation upon which the rail is to oe laid,the. sections being arranged end to end to ylorin a continuoushase-section. The head or tread sections are then placed in thehasesections, the web portions 8 of the sections 1 extendingr downwardlybetween. the wel)- langes 4t 4 ot' the sections '2, the heads or treadsQo'll the sections 1 'resting upon the top edges ot the weh-llanges 4 4of the sections 2. In placing` the head or tread sections 1 1 in thehasc-seet ions l the sections l are arranged whereby their confrontingends will ineet intermediate or centrally el" the sections 2, therebyproviding ar lirin and jointless hase for the, confront-ingr ends oi''the sections 1 1 and a irxn and solid head or tread for the confrontingends of the sections l it will thus he observed that the joints of theditierent sections throughout the rail are'alternate, first one iointbeing formed'in the sections 2 and then a joint in the sections 1.

To hold the sections 1 1 within the sections 3 2, nuts and holts 14 areemployed, and these bolts are placed in the openings of the haseseetionsl to engage in the openings or slots of the sect-ions 1. The openings orslots 10 1t) and 11 11 of the sections 1 are adapted to register withthe openings 6 6 and 5 5 of the web-flanges Lift of the sections 2. thismanner each section i will he locked at two places to the sections 2,and it will be imposot its adjoining sec-tions or the base-section whichsupports saiil sections. v

By toi-ming a rail of a plurality of sections l which are joinedtogether in the manner just TOO sible for one section 1 to moveindependently 'described it is possible to renew the tread 'or headsections of the rail Without removing the spikes that retain thebase-sections in engagement with the ties or foundation upon which. theyare mounted, it only heilig necessary to remove the bolts and nuts 14 oithe base-soetions in order to remove any head or -using the baseportions of a rail for possibly a plurality of head-sections, and inthis connection l. desire again to call attention to the fact that agreat Saving is incurred in the ties or' foundations which support myimproved rails.

I have allowed for the expansion and contraction ofthe sections of therails by providing the elongated openings or slots 1() 1l), l1 11, 5 5,and 6 in the sections of the rail, these opei'iings permitting 'of onesection to expand and contract relative to its adjoining section.

,lt will be observed in Fig. 4 oi the drawings that l have formed one ofthe head-see tions l integral with the base-section, thus providing arail whi'eh can be easily used in conneetion with a switch or frog, thebase portionioi the rail only being dispensed with for a portion el' itslength` in order that it may be secured to my improved rail-sections.

l do not care to confine n'iyscll to ar, y speeilie means ol' seeurii'igthe base-Sections to the ties or i'mindations which support them, andsuch changes in the construction of my improved rails as are permissibleby the appended claims may be resortedl to without departing from thespirit and scope of the invention.

What I elaiimand desire to secure by'Letters Patent, is

1. A rail of the type described, consisting of a plurality ofbase-sections, a plurality of separate head or tread sections, certainof said base-sections being formed with vertical web-flanges havinvertical openings formed therein, said treat -sections having webportions adapted to fit in the vertical openin sin the base-sections,certain other of said base-sections 'being formed with integral headsfor a portion of their length and said integral heads and theWeb-flanges of the last-named sections being prolonged beyond thebase-flanges thereof and seating in the vertical openings in theweb-flanges of the -first-named base-sections.v

2. A rail of the type described, consisting of a base-section, having aweb-flange with a yvertical opening therein, and a base-section havingan integral web and tread portieri, the web and tread portion of thelast-named section being prolonged beyond the baselanges thereof, andthe said prolonged web portion seating in the vertical opening in theweb-flange of the lirst-nanied section.

ln testimony whereof l aiiix my signature in the presence of twoWitnesses.
